Caution Before OrderingIf you are thinking of ordering this sink, please be aware that it weighs 46 pounds. After ordering, I found out from my countertop fabricator that they would have to mount the sink on site (not at their shop as they usually do with porcelain sinks). In addition, you will have to have extra support built into your vanity to support the sink. The countertop fabricators will not build the support. It is definitely a nice sink of high quality but it requires extra construction cost (not to mention losing valuable storage space under your sink).

Nice shape & depthThe unique shape to the sink makes is stand apart from the countless oval sinks you typically see. Love how deep it is...now I don't get too much splashing back up onto the counter as I did with my shallow cultured marble sinks. Only tiny detail I did not expect is the curvature of the sink where it meets the counter. The fit is not as snug as I'd like it but it still works as long as the silicon caulking is done well by installer. (Most sinks are straight on with the counter.)
